[OGD] Phal lindeni
Hi everyone, I have owned a Phal lindeni for several years and it has never had more than 2 or 3 leaves on it, although it blooms every year. I grow it mounted on tree fern with a sphagnum pad, and as it has been on that tree fern since I bought it the roots are fairly well integrated in the fibers. I keep it in about intermediate temps in my basement under fluorescent light. It annoys me that this plant always looks like it wants to jettison its leaves. Can anyone offer some advice on getting better results with this plant? Do you grow yours in pot/basket, cork, or TF? I sort of think my problem might be the tree fern as I’ve had problems with other species on tree fern in the past, but I know plenty of people use it with success. Thanks, Julia ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
Re: [OGD] viruses again
Thanks for doing that Cynthia. Open question: Does anyone have any other experience with the ELISA test (even in another line of work) so we can judge as to how correct it is?

Re: [OGD] Invasive non-natives
In a message dated 8/30/06 3:03:00 AM Pacific Daylight Time, Andy Easton writes:
"At the recent ASHS Summer meetings all the talk was about that the US is looking to follow the lead of two stupid countries, Australia and New Zealand, who currently operate a most restrictive control system for the importation of non-indigenous species. All the usual garbage is spouted about making sure they don't become invasive (most of us would love orchids to become invasive)"
Living in California, the danger of invasive nonnative plants is very obvious, and cannot be downplayed. The list of plants which are currently displacing native plants, reducing habitat and food for native animals and degrading agricultural land is huge. Eucalyptus species, Acacia species, Pampas Grass, Scotch Broom, Spanish Broom, Vinca Major, Vinca Minor, Algerian Ivy, Himalayan Blackberries, Senecio ("German Ivy"), Centranthus ruber, Star Thistle, are just a few in California. European Bittersweet, and Kudzu are a couple I know of in the East, but I am sure the list is much longer.
The notion that Orchids could become invasive or noxious weeds seems far fetched, but Zeuxine strateumatica has apparently established itself in Florida, and Epipactis helleborine has managed to spread across the entire country. The latter can be found in a surprising range of conditions in California; garden beds, lawns, roadside ditches, woodlands, dry slopes, and scrublands. The danger of nonnative orchids doing the same widespread damage as Eucalyptus or Pampas Grass is probably slight. But the possibility of them displacing native orchid species, and driving them towards extinction (given the other pressures on them) is worth considering. I have seen huge drifts of E. helleborine in a roadside ditch in one location, and given the number of seed pods they produce, it is worrisome. I like Epipactis h., but would rather see our native Epipactis gigantea, and Calyso bulbosa thrive, both in habitats that E. helleborine enjoys.
Past experience with invasive nonnative plants and animals shows we need to be more careful in the future. I have no doubt any new restrictions on plant importation will be a pain in the as for us all, but they are not necessarily "garbage".

[OGD] Blooming size Phragmipedium kovachii
The Slipper Orchid Forum shows pictures of Pk's in bloom at a well known Ecuadorian orchid collector. Someone else then responds by asking: " I just wonder why nobody selfing or cross this ecuadorian kovachii yet." This is how rumours get started. To date, to the best of my knowledge, no Pk habitat has been found in Ecuador. If ever it should happen, be assured that the world will know within hours. In the past few years, the Peruvian Ministry of Natural Resources, INRENA, has on several occasions confiscated flowering size Pk plants and other orchid species of many genera on their way to Ecuador and elsewhere. These were collected illegally in Peru. Phragmipedium kovachii habitats were discovered in the Department of Amazonas, Northern Peru. INRENA, has not yet issued a single export permit for mature Pk plants. At this moment, any blooming Pk outside the Peruvian nurseries of Alfredo Manrique and Manolo Arias is an illegal Pk. Legal Pk seedlings, propagated only by Centro de Jardineria Manrique and Peruflora, need to grow 5 to 7 years before they bloom for the first time. In 3-5 years from now, when the legal Pk seedlings have become flowering Pk plants, it will be very difficult to know if a flowering Pk is legal or illegal. I have a feeling that no one will waste any time then to find out.

[OGD] Julia Redman's query on Phalaenopsis lindenii
Julia, all I can think of is perhaps your plant is staying dry too long between waterings. have been growing Phal. lindenii for abut 5 years now. It resides on my living room window sill which faces southeast. The window is a low e, double paned affair, which doesn't allow appreciable heat to pass through. Lindenii is the only Phalaenopsis species I grow there but I have about five different Phal hybrids which share that window. I use no shading but the direct rays of the sun are diluted somewhat by the coppery tint afforded by the material between the panes. On the hottest days, the leaves do not feel warm, but the climate here on the southern Oregon coast is pretty mild.The lindenii is growing in a 4 in. plastic pot in medium bark with a small amount of coarse perlite added. I try not to let the mix get dry and hence water every second or third day.The plant has five leaves and none have been lost yet. An offset is developing at the base of the plant which blooms regularly every year about this time and in fact this year's inflorescence is about an inch long right now. I repot every other year. With frequent watering, the mix breaks down fairly rapidly. Marius ___ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
[OGD] Invasive Non natives
It matters little whether the introduced species is flora or fauna as the cost to Australia from these invasive non-native species is $3.3B per year and those figures are from 1997. This of course is only a monetary cost, the real cost is loss of native flora and fauna. Currently in New South Wales a proposal is under consideration for the introduction of Bombus terrestris (European Bumble Bee), to aid pollination rates in the Greenhouse industry and in particular, Tomato production. This pest was illegally released in Tasmania in the late 1980's and despite claims it would not spread, has colonised all World Heritage areas and most National Parks. It has spread at a rate of 25km per year and is found in low (600mm pa) and high (3200mm pa) rainfall areas and altitudes from sea level to 1260 mts. It was also introduced into New Zealand in 1885 to aid pollination of red clover but as in all other countries it has proved impossible to control. Do we need any more evidence?
